XF cuts out
I've got a '87 XF (dual fuel). Recently the old girl refused to run on gas (I think it has something to do with the solenoids as I don't hear them click when I turn on the ignition, anyhoo!), so I've just been running on petrol.
But for the last two days I've occasionally had the car not cough, but loose power for a few seconds when driving, then suddenly get back up and run again. It feels like the engine has just cut out and the car is coasting. The car hasn't stalled, but it seems to be very similar issue cropping up as was right before the gas failed for good.
Now my initial thought could perhaps be the fuel pump but my only experience with faulty fuel pumps is the car will run rough or revs move up and down. Then I was thinking with the electronic ignition is the ignition module about to fail?
Any help or pointers would be greatly appreciated. BTW, the car is a 4.1 carby + 3sp auto.
